COATING (For the detail, refer to M-System's web site.)
Moving parts and indicators are not coated.

Bezels are used to adapt the 48N Series to an existing panel cutout. In order to replace M-System’s 48 Series products, use the one attached to the 48N Series as standard.  When the existing panel is cut according to DIN standard, specify ‘/D’ suffix code.
For a new installation, no bezel is required. Please refer to ‘Mounting Requirement’ and mount the 48N directly.
Ingress protection is invalid when the 48N is mounted with a bezel, or when multiple modules are stacked side by side.
